INFRASTRUCTURE SOLUTION

GFRP for Water, Drainage & Utility Infrastructure

A practical corrosion-resistant option for concrete structures exposed to constant moisture and aggressive service conditions.

Where GFRP can add value

STPs and ETPs • Water tanks • Drains and channels • Manholes • Utility trenches

ENGINEERING NOTE

Water-retaining and buried structures require application-specific crack-width, serviceability and detailing checks.

IN PRACTICE

Reinforcement that water cannot touch

Water-retaining structures are the harshest environment for steel: permanent saturation, chlorination and effluent chemistry. GFRP rebar simply cannot rust, so tanks and drains stop leaking through corrosion cracks.

From STP digesters to storm drains, GFRP cages are prefabricated light enough to place by hand — even in confined manhole and channel works.

Where it’s used

Water tanks & reservoirs

Potable-safe, no leaching, no rust staining

STP / ETP structures

Survives chlorides, sulphides and acids

Storm drains & culverts

Long life under wet–dry cycling

Manholes & utility chambers

Light cages for confined-space installation

corrosion leak paths in saturated concrete

50%

less cover concrete needed in designs

100+ yrs

maintenance-free service life
